About the official source
This is a statewide map, not a county site. ORMAP statewide tax lot viewer (Oregon) covers parcels across Oregon, and Marion County is one part of it. Statewide parcel layers are usually stitched together from county files, so the newest splits or sales may show up on the county's own records first. Our October 2026 check found the map open to the public, with no account or payment needed.
Searching for a parcel, step by step
- Press the button to load the statewide viewer, then move the map to Marion County.
- Use the viewer's search tool to find an address or parcel, if it has one.
- Click a lot to read its details.
- For deeds, taxes or official copies, take the parcel number to the county's own offices.
Rural addresses don't always geocode well. When that happens, zoom in by hand and click the parcel, or search by owner name.

Before you rely on the lines
